then the next question, is how much nutrition does the celery need to continue growing… I’m assuming at some point, they would start yellowing from just sitting in water… would there be enough “ fertilizer” in aquarium water to grow each specific plant??? reading up on celery, it doesn’t provide much nutrition, it’s mostly fiber and water, so it may thrive without a strong fertilizer soup, where as broccoli or tomatoes may need a stronger fertilizer soup, than our fish could safely provide….
when I was farming tilapia in tanks outside a few years ago the tomatoes vine grew like crazy, however actual fruit production was low… I suspect the tomato needed a stronger fertilizer base to fruit heavily…. at the same time I did cucumbers, and while I didn’t get more cucumber fruit than I could eat, I got a lot more than the tomatoes produced… same light, and same water , I suspect the difference was related directly to each plant’s individual needs… celery looks to have less needs, to grow, and since we consume it, before it bears fruit, it’s needs may fall within the range of normal aquarium water… we may have better luck growing plants that we consume the plant, and not the fruit the plant produces… lettuce family, spinach cone to mind… I have my doubts on root vegetables that would have to be immersed in tank water, like potatoes, and carrots, for example… but even those may surprise us???
